Technologies to make things better.

Day: April 9, 2017

Seven days from now, we’ll celebrate Jesus’ sacrifice and resurrection with believers from all over the world. Join the millions who have already discovered how a short Reading Plan or Devotional inside the Bible App can help you refocus your mind and heart on Christ. Each one of these great Easter Plans is designed to help you and your family make the most of your time in God’s Word this Holy Week.

The conventional leather tanning technology is highly polluting as it produces large amounts of organic and chemical pollutants. Wastes generated by the leather processing industries pose a major challenge to the environment. According to conservative estimates, more than 600,000 tons per year of solid waste are generated worldwide by leather industry and approximately 40–50% of the hides are lost to shavings and trimmings.

Everyday a huge quantity of solid waste, including trimmings of finished leather, shaving dusts, hair, fleshing, trimming of raw hides and skins, are being produced from the industries. Chromium, sulphur, oils and noxious gas (methane, ammonia, and hydrogen sulphide) are the elements of liquid, gas and solid waste of tannery industries.

Biogas from Tannery Wastes

Anaerobic digestion (or biomethanation) systems are mature and proven processes that have the potential to convert tannery wastes into energy efficiently, and achieve the goals of pollution prevention/reduction, elimination of uncontrolled methane emissions and odour, recovery of bio-energy potential as biogas, production of stabilized residue for use as low grade fertilizer.

Anaerobic digestion of tannery wastes is an attractive method to recover energy from tannery wastes. This method degrades a substantial part of the organic matter contained in the sludge and tannery solid wastes, generating valuable biogas, contributing to alleviate the environmental problem, giving time to set-up more sustainable treatment and disposal routes. Digested solid waste is biologically stabilized and can be reused in agriculture.

Until now, biogas generation from tannery wastewater was considered that the complexity of the waste water stream originating from tanneries in combination with the presence of chroming would result in the poisoning of the process in a high loaded anaerobic reactor.

When the locally available industrial wastewater treatment plant is not provided by anaerobic digester, a large scale digestion can be planned in regions accommodating a big cluster of tanneries, if there is enough waste to make the facility economically attractive. In this circumstance, an anaerobic co-digestion plant based on sludge and tanneries may be a recommendable option, which reduces the quantity of landfilled waste and recovers its energy potential. It can also incorporate any other domestic, industrial or agricultural wastes. Chrome-free digested tannery sludge also has a definite value as a fertilizer based on its nutrient content.

Potential Applications of Biogas

Biogas produced in anaerobic digesters consists of methane (50%–80%), carbon dioxide (20%–50%), and trace levels of other gases such as hydrogen, carbon monoxide, nitrogen, oxygen, and hydrogen sulfide. Biogas can be used for producing electricity and heat, as a natural gas substitute and also a transportation fuel. A combined heat and power plant system (CHP) not only generates power but also produces heat for in-house requirements to maintain desired temperature level in the digester during cold season.

CHP systems cover a range of technologies but indicative energy outputs per m3 of biogas are approximately 1.7 kWh electricity and 2.5kWh heat. The combined production of electricity and heat is highly desirable because it displaces non-renewable energy demand elsewhere and therefore reduces the amount of carbon dioxide released into the atmosphere.

AD Plant at ECCO’s Tannery (Netherlands)

A highly advanced wastewater treatment plant and biogas system became fully operational in 2012 at ECCO’s tannery in the Netherlands. A large percentage of the waste is piped directly into the wastewater plant to be converted into biogas. This biogas digester provides a source of renewable fuel and also helps to dispose of waste materials by converting waste from both the leather-making processes, and the wastewater treatment plant, into biogas. All excess organic material from the hides is also converted into biogas.

This project enables ECCO Tannery to reduce waste and to substitute virtually all of its consumption of non-renewable natural gas with renewable biogas. The aim is to use more than 40% of the total tannery waste and replace up to 60% of the total natural gas consumption with biogas.

Plan to make use of your MSW or agro-industrial organic waste to generate power or have W2E projects?

We do local turnkey biogas power plant projects. We offer expertise and experience of one of the top ten biogas engineering and construction company in the world- a Germany based corporation with over 400 installed biogas power plants worldwide.

We are looking forward to serve you in converting your waste into resources.

Managing those assets means figuring out how to best take advantage of the batteries.

“We will experiment with how to utilize those batteries,” Smith said. The co-op can control the rate at which energy is stored in the batteries, she added.

“We are testing various distributions of that stored power; we will look at the rate at which batteries download stored energy,” she said. The co-op is testing ways to use the stored energy and comparing the cost of those options with the cost of the diesel generator plant.

Local or remote real-time operational data monitoring is the precursor of the 4th industrial revolution and IoT (Internet of Things). The power of data when you need it, where you need it. Space and time constraints totally eliminated.

We have done above subject for high rise and commercial building BMS and FDAS. Industrial HMI and Automation. Marine vessel instrumentation. Wind, Solar, and Biomass Power Plant local and remote SCADA- generation capacity of 12KW to 50MW.

Blessed is he who comes in the name of the Lord. Blessed is the king of Israel

Let us go together to meet Christ on the Mount of Olives. Today he returns from Bethany and proceeds of his own free will toward his holy and blessed passion, to consummate the mystery of our salvation. He who came down from heaven to raise us from the depths of sin, to raise us with himself, we are told in Scripture, above every sovereignty, authority and power, and every other name that can be named, now comes of his own free will to make his journey to Jerusalem. He comes without pomp or ostentation. As the psalmist says: He will not dispute or raise his voice to make it heard in the streets. He will be meek and humble, and he will make his entry in simplicity.

Let us run to accompany him as he hastens toward his passion, and imitate those who met him then, not by covering his path with garments, olive branches or palms, but by doing all we can to prostrate ourselves before him by being humble and by trying to live as he would wish. Then we shall be able to receive the Word at his coming, and God, whom no limits can contain, will be within us.

In his humility Christ entered the dark regions of our fallen world and he is glad that he became so humble for our sake, glad that he came and lived among us and shared in our nature in order to raise us up again to himself. And even though we are told that he has now ascended above the highest heavens—the proof, surely, of his power and godhead—his love for man will never rest until he has raised our earthbound nature from glory to glory, and made it one with his own in heaven.

So let us spread before his feet, not garments or soulless olive branches, which delight the eye for a few hours and then wither, but ourselves, clothed in his grace, or rather, clothed completely in him. We who have been baptized into Christ must ourselves be the garments that we spread before him. Now that the crimson stains of our sins have been washed away in the saving waters of baptism and we have become white as pure wool, let us present the conqueror of death, not with mere branches of palms but with the real rewards of his victory. Let our souls take the place of the welcoming branches as we join today in the children’s holy song: Blessed is he who comes in the name of the Lord. Blessed is the king of Israel.
